Generated images of smaller pixel dimensions have larger file size than original

    I’m not sure why comments to this topic: https://wordpress.org/support/topic/resized-images-much-bigger-than-original-ones/ are closed, but I’m having the same issue. I’m carefully optimizing my images, and then noticing WordPress generating alternate sizes that are smaller in terms of pixels, but larger in terms of filesize. The end result is that mobile pages are actually heavier than desktop pages. Not good.

    Does anyone know of a plugin that does a better job of generating different image sizes? Or anything else that might fix this?

    That happens when the quality settings for imagemagick (the server-side library WordPress uses to create images) are too high. I honestly have never understood the “physics” of that myself, but you can do the same thing by exporting any smaller image in Photoshop (or any other image editor) at 100% quality, it’s just a thing that happens, and yeah it’s weird.

    Anyway, if you have access to your server configuration, knock imagemagick down to something like 80%.

    If you don’t have access to your server configuration, use a plugin like https://wordpress.org/plugins/image-quality/ or many others: https://wordpress.org/plugins/search/image+quality/
